When nearly an inch long they ate tlie grass through, generally from the tops 
downwards, remaining on it by day if their glass covering was shaded, but other* 
wise hiding close to the roots. 
The most forward one was full grown by the 14th March, and the latest by 
30th May, 1866, the perfect insects appearing from June 4th to July 9th. The 
larvae are cylindrical, ground colour ochreous, greyish, or greyiah-ochreous, with 
a whitish dorsal line outlined with dark grey running through the middle of an oval 
shape of brownish-grey on each segment. 
Sub-dorsal, Hne whitish, margined above with a greyish stripe, and below by a 
thin brownish hne, and after an interval of the ground colour, another fine line of 
brown, edged below with a thin line of pale ochreous, followed by a broad stripe of 
greyish, the black spiracles being along its lower edge ; below is a broad stripe 
of pale ochreous ; belly and fore-legs ochreous-grey ; ordinary dots along the back 
dark brown, and very small. Head mottled with grey-brown. — W. Buckler, 
Emsworth. 
Description of the larva of Acidalia contiguaria. — Through the kindness of 
Messrs. Greening and Bond, Mr. Buckler and myself have had the pleasure of 
rearing the larva of this species this season. 
The larva, after hybernation, at the beginning of April, was about half-an-inch 
in length ; and at that time, although rugose, and presenting a most decided wave- 
like appearance, was not at all so plainly marked as it afterwards became. The ground 
colour was a warm ochreous-brown above, and a dark chocolate brown beneath ; 
and on the middle segments was a row of elongated diamond-shaped markings, 
slightly darker than the ground colour, with the four usual dots on each segment 
blackish ; along the spiracular region the dark and light shades of brown met in a 
sort of zig-zag line. 
About April 20th the larva moulted for the last time, and after that continued 
to feed for about four weeks. 
When full-fed it was about three-quarters of an inch in length, belonging to 
the shorter and thicker type of Acidalia larvae, rather flattened below, slightly 
tapering from tail to head, rugose ; the head small and bifid. The back of a buff- 
brown, brighter on the head and three following segments ; a dark sub-dorsal (but 
no dorsal) line on these same segments; at segment five the sub-dorsal Hne ceases, 
and the dorsal row of dark-brown elongated diamonds begins ; this contracts to a 
double dorsal line, but is much darker, on the hinder segments ; the usual dots 
black, emitting bristles ; the spiracular region puffed and puckered, bordered 
below with a broad irregular stripe of dark brown ; the centre of the belly of an 
ochreous-brown. 
When disturbed the larva draws back the front segments, but I did not see it 
twist into a coil. 
Understanding that the food must be Empetrum nigrum, we troubled our 
friends to send us a supply of this plant out of Yorkshire, and then soon found that 
ling, whitethorn-buds and Polygonum aviculare were just as acceptable ! The two 
moths emerged on June 27th and July 5th. — J. Hellins, July I2th. 
Trochilium chrysidiforme at Folkestone. — During three weeks' stay at Folkestone, 
I met vdth several fine specimens of this beautiful clearwing. — E. Meek, 5, King 
Street, Old Ford Road, N.E.
